. mechanism for flush tanks. A

.In the existing .types'of water controlling, mechanism, the'valve member for closing the outlet is usually a rubber float attached to a:

Y My inventionrelates to water controlling wire: rod 'slidablein a bracket. This valve member as it moves into position to close the water outlet, often sticks in the bracket, ordoes not properly seat on the outlet, in which outlet'valve' to close the outlet." Failure of the outlet valve-tto'close-results in loss of water and objectionable noise.

'case the tank 'does not fill and the inlet valve does not close until someone manipulates the The Tobject's of'my invention are to pro vide water controlling mechanism of simple and durable construction in which the valve member will positively move into position to close the outlet; which may be quickly installed in any type of flush tank, and which may be adjusted to fit diflerently proportioned tanks.

These objects and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a sectional plan view through a flush tank having my invention applied thereto,

Figure. 2 a vertical section through the tank shown in Figural illustrating the water controlling mechanism in full,

Figure 3 a section on line 33 of Figure 2, and

Figure 4 a fragmentary section on line /14 of Figure 2.

Referring to the drawings, 1 indicates the flush tank, 2 the outlet, 3 the overflow pipe connected with the outlet, 4 the float controlled valve, 5 the float connected to the valve, 6 the arm connecting the valve and the float, 7 the water inlet and 8 the hand operated lever for flushing the tank.

My controlling device is attached to overflow pipe 3 and lever 8, and operates in con- -1924; Serial No. 721,978.

junction with .the float arm 6 to close the outlet 2 when the 'water in the tank drops to I -justment: and having a pair of' arms 10 which slidably receive-a rod 11 having its upper end connected to-lever8 and carrying at its lower end a valve member l2-for closing ioutlet '2. A collar 13 is adjustably' mounted on rod llbetween the arms 10. A

springnlt, coiled around the rod and dis- 'poseclTbetween the collar and'the'upper arm, normally holds the rod andvalve member 12 in position to ,close the outlet. A bell crank lever 15 is pivoted to the lower arm 10 and has one arm 16 passing through a projection 17 on collar l3'and notched at'18 .to-engage. and catch over a ledge-19 within the "projection; A coiled spring 20' in the lower-arm normally presses arm' 16 against ledge 19 so that when collar 13 is'raised to the level of notch 18. the notch will'catch over the ledge and hold the collar in its raised position. The other arm 21 of the bell crank lever extends outwardly into the path of arm 6 which carries float 5. As the water level in the tank falls, arm 6 willengage with extending arm 21 of the bell crank lever and move notched arm 16 out of engagement with ledge 19 thereby releasing the collar and allowing spring 14 to act to force rod 11 and valve member 12 downward to close the'outlet. The valve member preferably extends radially from rod 11, as shown in Figure 4 so that it may be positioned to close differently positioned outlets.

I have shown the valve member as consisting ofa metallic backing plate 22 and a resilient plate 23, preferably rubber, secured against an enlargement 2& on the lower end of rod 11 by a nut 25.

To install my controlling mechanism, bracket 9, with rod 11, bell crank lever 15 and their associated parts properly connected thereto, is slipped over pipe 3 and clamped in position by tightening set screw 26. Valve member 12 is adjusted by moving it until the outlet is properly closed. This may be effected by loosening set screw 27 in collar 13 to allow rod 11 to turn. Collar 13 is then adjusted on the rod so that when the rod is raised ledge 19 will engage the notch 18 of the bell crank lever and secured in position by set screw 27. and the upper end of rod 11 connected to lever 8. The mechanism is ready for use.

In use, lever 8 is manipulated to raise the rod until ledge 19 engages the notch 18 in the end of the bell crank lever. This movement brings valve member 12 from the full line position shown in Figure 2 to the clotand-dash line position and opens outlet 2. As the water level in the tank falls, float carrying arm 6 will engage with arm 21 of the bell crank lever and actuate the lever to force notch 18 out of engagement with ledge 19. This releases collar 13 and allows valve member 12 to be moved into closing engagement with the outlet by spring 1 1. \Vater coming from valve 4 gradually fills the tank and raises float 5. After float 5 has been raised a predetermined distance, valve 1 is closed.

It will be seen that with the controlling mechanism above described, the valve memher will not stick or improperly seat on the outlet, and loss of water, objectionable noise and the necessity for occasional hand manipulation are avoided.

lVhile I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. Water controlling means in flush tanks including an out-let; a bracket mounted in the tank; a rod .slidable in the bracket; a radially extending and swingably adjustable valve member carried by the rod for closing the outlet; means for moving the rod, and tripping means for releasing the moving means whereby the valve will-be moved to close the outlet when the water in the tank drops to a predetermined level.

2. lVater controlling means in a flush tank including an outlet; a bracket mounted in the tank having spaced arms; a rod slidable in the arms; a valve member carried by the rod for closing the outlet; a collar adjustable on the rod between the arms; resilient means between the collar and the upper arm; a bell crank lever pivoted on the lower arm and having one arm adapted to engage and hold the collar against the action of the resilient means; a float controlled inlet valve, and an arm connecting the valve and the float, the arm being adapted to engage the other arm of the bell crank lever to release the collar whereby the valve member will close the outlet when the water in the tank drops to a predetermined level.

In testimony whereof I have signed my name to this specification.
